MCQ
A hollow glass prism gives:
  • A
    A dim spectrum
  • B
    Bright spectrum
  • C
    No spectrum
  • D
    Only continuous spectrum
✓

Answer

  1. No spectrum

Explanation:

A hollow glass prism does not give any spectrum because it does not have any medium inside it is hollow from inside so white light can not split in vacuum because in vacuum all colors light travel with same speed hence they do not split and no spectrum is observed.
